The following table shows the mean and standard deviation of each stock's annual return. Distributions of Returns Mean Standard Deviation Apple 16% 21% Microsoft 12% 13% Tesla 25% 38% Costco 18% 20% The correlations between the annual returns on the four stocks are as follows. Correlation Matrix Apple Microsoft Tesla Costco Apple 1 0.75 - 0.7 0.2 Microsoft 0.75 1 -0.2 0.5 Tesla -0.7 -0.2 1 0.65 Costco 0.2 0.5 0.65 1 You can assume that he has invested equal amounts in each of these stocks. Also it is safe to assume lognormal distribution for each of the stock returns. Use the above simulation model to estimate the probability that Dr. N’s portfolio will lose money in one year.

Jake’s car dealer is trying to determine how many model 2024 cars to order. Each car ordered in September costs $45,000. The demand for the new electric cars has the following probability distribution. Each car sells for $54,000. If the demand for 2024 cars exceeds the number of cars ordered in September, Jake must reorder at a cost of $50,000 per car. Excess electric cars can be salvaged at $39,000 per car.
